Introducing Astell&Kern’s new flagship, A&ultima SP2000. The SP2000 is the first Astell&Kern player to use separate, independent audio channels between the Unbalanced and Balanced outputs. This design offers much more power than ever before, with 6 Vrms for Balanced output and 3Vrms for Unbalanced output. The AK4499EQ DAC chip uses the most advanced ‘Current Output Architecture’ technology. To take full advantage of this new architecture, Astell&Kern redesigned the Op Amp and analog amp block configuration completely. The new circuit design optimizes the current consumption and brings out the most from these new DAC chips. The combination of the SP2000 and AK4499EQ chips provide mind-blowing audio quality.SP2000 is the first Astell&Kern model to support 32 bit/768 kHz and DSD512 (22.4MHz) playback natively without compression or loss. With streaming music services becoming more popular, stronger and more reliable network reception becomes even more important for your audio experience. The SP2000 supports Dual Band Wi-Fi (2.4/5GHz, a/b/g/n/ac) with an improved 3-dimensional antenna design. With a stronger Wi-Fi signal and faster speeds, music streaming from the most popular services is better than ever on the SP2000. When it comes to CD-ripping and offline storage of streaming content, the SP2000 offers 512GB internal storage can hold 700+ CDs or 8,000+ tracks of FLAC files (60MB/track).
